D. ALTMAN PAPER BAG Filed Sept. 19, 1931 jrwenior DAVID ALTMAN Patented May 23, 1933 UNITED smras m DF-FJCE DAVID ,ALTMZAN, F BALTIMORE, MAR-YLAN D, ASSEI'GNORTOF PER CENT 'DO MEYER QAIZIJDSQN, 0F BALTIMORE, MARYLAND PAPER'BA'G Application fired Septem ber This invention relates to pa'per bags, bones and containers in genera/land more particulairily to imprwements in the construction thereof for facilitating the sealing of the same.

Among the principal objects of the present invention is to provide means in a container, such as a paper bag, for sealing the normally open end thereof, this sealing 40 means being of such character as to eliminate the necessity of tying the filled container with string or the like.

A further object of the invention is the provision of a gummed area centrally located at the top of one of the panels of the container such that when the same is filled and the top ends thereof are folded over in the usual manner, the gummed area may be moistened and permanently secured in place to seal the container.

A still further object of the invention is to provide a standard paper bag with a gummed area centrally located in the top end of one of the panels of the bag, this gumined area being of such character that after it has been secured in place to seal the bag, the latter may be readily opened to remove the contents thereof without destroying or injuring that portion of the bag to 80 which the gummed area Was secured.

Other objects and advantages of the invention will be apparent hereinafter.

The invention consists substantially in the combination, construction, location and relative arrangement of parts, all as will appear more fully hereinafter, as shown in the accompanying drawing, and as finally pointed outin the appended claims. In the accompanying drawing, the invention has been shown, for purposes of illustration, as incorporated in a paper bag. It will be understood, of course, that the invention may as readily be incorporated in other containers, such as paper boxes and the like, which are characterized by the provision of an openable flap, and it is not intended therefore to limit the application of the invention solely to the form of container illus- 150 trated in the drawing.

19,1931. Serial *No. '5635689.

In the accompanying drawing:-

Figure 1 is azperspectiive view of an ordinary paper bag embodying t'he present invention, the bag being shown fi'l'led with material and "with the top there'of sealed;

Figure 52 is a perspective view of the bag shown in Figure 1 as itapspeairs when in Ifia't condition and rpnior to being filled; I

Figures 3 and 4 are views similar to that of Figure fl sho wi ng modi fied forms of the gummed areas;

Figure 5 is-a perspective view-ofthe upper end of a bag showing a still lfuirt'he'r modified form of guinmed area; and

Figure 6 is a perspec'tivie view of the top end of a 'filled bag showing the seal breken preliminarily to removing-the con tents therefrom.

Referring now to the drawing and more particularly (to Figures 1., i2 and 6, it will be 'obsenved that the zitnvention has been embodied in :a container which in the instance i liltrstratetl is in the farm of a bag 19 *of standard form having back and front panels l1 and 12 and side plaits *13- *13, these side plaits being respectively adapted to be folded inorder to permit the bag to be collapsed into the substantially "fiat foirm shown in Eignire 2. 71:11 standard of bag, the back panel or wall 11 thereof *is usually of greater 'le th than and extends above the top edge 0 the fn'ont panel or wall 12.

Provided in the back panel 11 ri imned iaitely adiacent the 'tep edge thereof is a centrally located area or none 14 the inner surface of which is gamined. As appears most clearly in Figure "2 this 'gamined area 14 may be of triangular shape, the "area thereo'f being defined by t'lrepe'rforated lines 15 and I6 and the top edgeof the panel 11. Inthe use of this bag, the latter is first expanded in the usual manner and then filled with the material to be contained therein whereupon the open top or mouth of the bag is folded upon itself as show-n most clearly in Figure 1 and in such manner as to leave the *gummed area 14 fnee to be secured to the external surface of the f rontwpane'l "12 of the bag. It will be understood'ithat this gum-med area 14 is readily secured to the panel 12 upon moistening the adhesive material.

In order to open the bag and so permit the removal of the contents therefrom, it is merely necessary to tear open the sealed top flap along the perforated lines 15 and 16. It is important to note that in so breaking the seal the gummed area 14 remains secured to the front panel 12 of the bag (see Figure 6), thereby obviating the likelihood of tearing the panel 12.

In Figure 3 the gummed area 14 is of circular form, while in Figure 4 the gummed area 1 1" is of rectangular form. In both of these modifications the gummed areas are rendered readily separable from the panel or Wall 11 of the bag through the provision of perforated lines similar to those provided in the form of bag shown in Figure 2. Instead of providing perforated lines for facilitating the separation of the gummed area of the bag from the remaining portion thereof, scored lines 17 may be provided as shown in Figure 5.

By means of the present invention,.the necessitv fm" using twine is eliminated as is the pOSslbillI) :f tearing the bag below the mouth thereof as when an odinary sealing flap is employed. Perforated or scored lines which circumscribe the gummed areas make it possible to open the top of the bag without rendering the same useless after it has once been opened. It will be understood of course that the invention is susceptible of various changes and modifications from time to time without departing from the real spirit or general principles thereof, and it is accordingly intended to claim the same broadly, as Well as specifically, as indicated by the appended claims.

What is claimed as new and useful is 1. In a paper bag, in combination, a pair of main walls the vertical edges of which are respectively interconnected-by side plaits,

a gummed zone provided in the upper portion of one wall of the bag for adhesive securement tothe other wall thereof, and means circumscribing said gummed zone for rendering the same bodily separable from the surrounding portion of the Wall in which it is provided, the upper edge of said gummed zone being coincident with the upper edge of the wall last mentioned.

2. A paper bag of the character described comprising front and rear walls and interconnecting side laits, one of said walls being provided adjacent the upper edge thereof with an area the inner surface of which is coated with adhesive material, and means circumscribing said area and terminating in said upper edge for rendering the same bodily separable from the surrounding portion of the wall in which it is provided.

3. A paper bag having front and rear panels and interconnecting side plaits, the

upper portions of said panels and plaits being foldable, when the bag is filled, as to provide one of said panels with a top flap having a free edge overlying the other panel, said flap being provided 011 the inner surface thereof with a gummed area adapted to be sealed to the underlying panel of the bag, the outer edge of said gummed area being substantially coincident with said free edge of the top fiap, and means circumscribing said gummed area terminating in said free edge for rendering the same bodily separable from the surrounding portion of the flap when the latter is separated from said underlying panel.

In. testimony whereof, I have hereunto afiixed my signature.
